The market makers don't matter. There may be a good ask-bid spread, but, no one besides market makers are trading.
I'm guessing we are all waiting for the buyout notice POW! is supposed to send out 20 days before voting. It should contain disclosure material to determining whether people should go for their dissenter rights. Maybe we minority shareholders will finally be privy to some details to the (super) secret deals Stan Lee has been making.
Camsing is up to HK $4.82, more than HK $2 above the share price before announcing a POW! buyout. It's more than a 70% increase, market cap increase of about HK $2 billion (about $260 million US). There has been active trading among the largest shareholders (insiders?). I'm guessing they value POW! a lot more than the buyout price.
And, FYI, to people contemplating suing, you may want to start the lawsuit while you are still a shareholder, not after the buyout.A lot of your rights go with selling your shares.
Edit
We might see trading pick up after the disclosure is made. And/or, we might see lawsuits filed after the disclosure is made. We won't know until it happens. Both Camsing and POW! have been quiet lately.
